Adds support for own toolbar and uploader templates

[codingluke]

Hi @ejholmes I came across this great gem. But for my client its very important to customize the UI. So I just added the possibility to configure the templates "toolbar" and "uploader". I also added a description. What do you thing about this?

Custom template paths

The toolbar and the uploader are client side templates (ejs) To customize these you can set custom paths your very own templates. Its important that the template has a different name then (toolbar or uploader)!

ActiveAdmin::Editor.configure do |config|
  config.template_paths = {
      toolbar: 'path to my custom toolbar template',
      uploader: 'path to my custom uploader template'
  }
end

Please check the original templates for an example app/assets/javascripts/active_admin/editor/templates

Make your templates available

Unfortunately sproket can not find templates from your asset folder when requireing them in a gem. So you have to make your templates manually avaliable.

//= require_tree ./path_to_your_templates

Hey @codingluke. I've been pretty busy, but I'll try to get a look at this sometime in the next week.

Hi @ejholmes no problems just take you time!

So, I probably won't merge this. I think the issue is that we use require_tree instead of require. I think straight up requires would fix the problem so you could easily override the templates in your app.

Your right I had this idee too. I just searched for a solution which dont bearks actual code. Im looking forward for your new solution.

Oh, I missundersood it. Dont you think the require should be on the users asset pipeline for that the override works? I just have the feeling that I is not working because the require_tree is on the gems asset pipeline. I will also investigate in this by interest.
